摘要

摘要: 以价廉量广的乙烯焦油的重馏分油（>250℃）为原料，以三聚甲醛为交联剂合成耐热性优异的缩合多核芳香烃树脂（COPNAR）。基于1H-NMR分析，采用改进的B-L法对重馏分油和乙烯焦油的平均分子结构进行解析。采用FT-IR、1H-NMR、TGA和元素分析等研究了所制COPNAR的基本性质和合成机理。结果表明，乙烯焦油的重馏分油可用来合成具有优异耐热性的COPNAR。对乙烯焦油进行蒸馏，可显著提高所制树脂的耐热性。反应机理为酸催化阳离子缩聚反应。

Abstract: Heat-resistant condensed poly-nuclear aromatic resin (COPNAR) was prepared using heavy distillate (>250℃, named DO) from distilled ethylene tar (ET). The basic properties of ET, DO and COPNAR were investigated by FT-IR, 1H-NMR, TGA and elemental analysis. The structural parameters of DO and ET were obtained by the improved Brown - Ladner method and the formation mechanism of the COPNAR from DO was deduced. Results show that a superior heat-resistant COPNAR can be obtained from DO. The distillation of ET increases the heat resistance of the COPNAR, and the reaction mechanism is confirmed to be an acid-catalyzed positive ion-type polymerization.
